Product detailed description

💨 Sonoff SAWF-08P - Matter CO₂ Air Quality Sensor

The SONOFF AirGuard CO₂ (SAWF-08P) is an advanced air quality monitor supporting the Matter over Wi-Fi protocol. It utilizes CO₂ sensing technology based on a precise NDIR sensor capable of measuring and displaying carbon dioxide levels, temperature, and humidity in real-time.

The professional NDIR sensor updates every 5 seconds, reacting swiftly to changes in indoor air quality with an impressive accuracy of ±(50 ppm + 5%). Elevated CO₂ levels in poorly ventilated spaces can cause drowsiness, fatigue, and poor concentration. Tracking and reducing these levels (e.g., through timely ventilation) will help you feel more awake and focused.

Personalized Alerts and Protection

Receive instant notifications about deteriorating air quality through 3 methods: App push notifications, audible alarms on the device, and visual LED warnings on the sensor. Customize your preferences and set a "Do Not Disturb" mode to avoid interruptions at night or when you need peace and quiet.

Historical Data and Export

With local and cloud storage of historical data for up to 1 year and data export functionality, the AirGuard CO₂ supports long-term analysis of your environment. Visualize trends on intuitive in-app graphs to pinpoint the root causes of air quality changes and develop healthier, energy-efficient ventilation habits.

Full Matter and Apple HomeKit Integration

Thanks to native Matter standard support, the AirGuard CO₂ can be seamlessly integrated with major ecosystems such as Apple Home, Google Home, Amazon Alexa, and SmartThings. The measured values can also be used in smart automations—for example, to automatically trigger ventilation systems, window openers, or fans when CO₂ levels become too high.

*Note: Integrating the sensor into a third-party Matter ecosystem requires a corresponding Matter Hub (e.g., Apple TV, HomePod, Google Nest Hub).

Voice Control and Hands-Free Access

This sensor is designed to seamlessly blend into your ecosystem. It fully supports voice assistants like Siri, Google Assistant, and Alexa. Hands-free air quality checks allow users to get immediate environmental status updates without needing to open an app on their phone.

Feature Overview

*Note: To view humidity data in the Apple Home app, ensure your iPhone is updated to the latest iOS version.
